N. nucifera is one among the important medicinal plants assessed for its antiobesity action in various preclinical models. The present study was aimed at investigating the antiobesity effect of methanol and successive water extracts of petals of N. nucifera by studying its effect on adipogenesis, adipolysis, lipase, serotonin (5-HT2C), cannabinoid (CNR2), melanocyte concentrating hormone (MCHR1), and melanocortin (MC4R) receptors. Both methanol and successive water extracts of N. nucifera petals had an effect on inhibition of lipid storage in adipocytes and on increasing lipolysis. N. nucifera petal methanol extract exhibited the concentration-dependent inhibitory effect on lipase activity with an IC50 value of 47 µg/mL. N. nucifera petal extracts showed evident agonist and antagonist activity towards 5-HT2C and CNR2 receptors, respectively, while it showed no effect towards MCHR1 and MC4R receptors. Overall, methanol extract of N. nucifera petals showed better activity than successive water extract.

Background: Lotus (Nelumbo nucifera) is a significant aquatic ornamental genus widely utilized in horticulture for its decorative, culinary, medicinal, and other practical uses. It presents a variety of flower shapes, including few-petalled, semi-double-petalled, double-petalled and thousand-petalled flowers, making it an ideal candidate for studying the flower development of aquatic plants. However, the molecular mechanism of floral development in lotus remains elusive.

Premise: Nelumbo nucifera is one of several plant species with flowers that typically open in the early morning and close by noon. This movement normally repeats for 3 days, with all petals falling off on day 4. However, detailed observations of flower movement in Nelumbo species are limited.

Article Synopsis
- - The study investigates the genetic basis of plant architecture traits in the lotus plant (Nelumbo nucifera G.) by analyzing seven specific characteristics through genome-wide association analysis (GWAS) in 301 lotus accessions over four years.
- - Researchers identified 90 genetic loci associated with these architecture traits and conducted RNA sequencing to find differential gene expression between large and small plant architectures, pinpointing eight key genes related to cell wall remodeling.
- - Results show that large plant architecture varieties have higher cellulose and hemicellulose content, while small varieties contain more pectin and lignin, indicating that cell wall composition significantly influences plant architecture, offering resources for future breeding efforts.

The objectives of this study were (1) to investigate the effect of extracts from some plants in the families Nelumbonaceae and Nymphaeaceae on phosphodiesterase 5 (PDE5) and arginase, which have been used in erectile dysfunction treatment, and (2) to isolate and identify the compounds responsible for such activities. The characterization and quantitative analysis of flavonoid constituents in the active extracts were performed by HPLC. Thirty-seven ethanolic extracts from different parts of plants in the genus and of Nymphaeaceae and genus of Nelumbonaceae were screened for PDE5 and arginase inhibitory activities.
